A compressed air system can be installed quickly and easily, compared with other installation methods, time savings of at least 50% are easily achievable. 05

Complex systems can be assembled much more rapidly than with traditional methods and because fittings are easy to disconnect, systems can be altered or extended with much reduced production down time.

28MM FITTINGS Pipe • • • Collet Screw Cap • Body 28mm fittings also have a collet with stainless steel teeth and an ‘O’ ring. After inserting the pipe, a screw cap is turned approx 1/4 turn. This locks the collet in place and reduces lateral and sideways movement of the pipe. To disconnect, turn the screw cap 1/4 turn, push in the collet and remove the pipe. The fitting and pipe can be reused. Nylon, Copper & Aluminium Pipe Whilst we recommend the use of John Guest Rigid Nylon Pipe, John Guest Fittings can also be used with copper or aluminium pipe. www.johnguest.com 10
